Saving JTable edits to an array
I know this question has been asked but after reading the other answers I still did not quite understand exactly what I need to do.
I have created a massive JTable (60 columns and a dynamic amount of rows) that holds data after being parsed from an XML file with a DOM Parser.
The idea is that the user should be able to edit the fields in the table and then the click a save button and a new XML will be generated reflecting the changes.
The problem is that when the user click saves and the action listener tells all the arrays/strings that had the original XML values copy all of the cell values, only the old cell values are copied even if they have been changed.
I have read other posts where people advised using a different table model but I'd really prefer not to do this if possible. As I've already finished the table I hate to backtrack and am hoping for an easier fix.
I'll attempt to shorten my code for your convenience.
public static int counter;
public static int counter2;
public static JTable tbl;
public static int currentRow;
public static void createGUI(){
counter=XMLParser.NtryRefAL.size();
counter2=counter;
final JFrame frame = new JFrame("CamT54 Builder");
JPanel mainPanel = new JPanel(new BorderLayout());
JPanel panelNorth = new JPanel(new BorderLayout());
JPanel panelSouth = new JPanel(new BorderLayout());
JPanel buttonPanel = new JPanel(new FlowLayout());
JButton uploadButton = new JButton("Upload");
uploadButton.setPreferredSize(new Dimension(150,40));
buttonPanel.add(uploadButton);
JButton saveButton = new JButton("Save Changes");
saveButton.setPreferredSize(new Dimension(150,40));
buttonPanel.add(saveButton);
//Creates the JTable
tbl = new JTable();
DefaultTableModel dtm = new DefaultTableModel(0,0);
String header[] = new String[]{//All 60 column headers are here};
dtm.setColumnIdentifiers(header);
tbl.setModel(dtm);
for(int count = XMLParser.NtryRefAL.size(); count >0; count--){
dtm.addRow(new Object[]{XMLParser.MsgRcptS,XMLParser.CreDtTmS,XMLParser.MsgIdS,
//I add more values for each of the columns here, the loop is for each row.}
XMLParser.NtryRefAL.remove(0);
XMLParser.AmtCcyAL.remove(0);
//Continue to remove the array values so they
can be replaced with the cell values.
}
tbl.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
tbl.getColumnModel().getColumn(0).setPreferredWidth(150);
tbl.getColumnModel().getColumn(1).setPreferredWidth(150);
tbl.getColumnModel().getColumn(2).setPreferredWidth(150);
tbl.getColumnModel().getColumn(3).setPreferredWidth(150);
tbl.getColumnModel().getColumn(4).setPreferredWidth(150);
tbl.getColumnModel().getColumn(5).setPreferredWidth(150);
tbl.getColumnModel().getColumn(6).setPreferredWidth(150);
tbl.getColumnModel().getColumn(7).setPreferredWidth(150);
tbl.getColumnModel().getColumn(8).setPreferredWidth(150);
tbl.getColumnModel().getColumn(9).setPreferredWidth(150);
//Set the rest of the column widths..
uploadButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
FileHandling fHandling = new FileHandling();
fHandling.getFile();
XMLParser parse = new XMLParser();
parse.parseXML();
frame.dispose();
MainGui.createGUI();
}
});

}

wParser.reWrite();
//Rewrites the XML values with the new array list values. This part works
//it just doesn't write the values I want because they aren't being saved.
}
});
panelNorth.add(tbl);
panelNorth.add(new JScrollPane(tbl));
panelNorth.setPreferredSize(new Dimension(500,500));
panelSouth.add(buttonPanel,BorderLayout.NORTH);
mainPanel.add(panelNorth,BorderLayout.NORTH);
mainPanel.add(panelSouth,BorderLayout.SOUTH);
frame.add(mainPanel);
frame.setVisible(true);
frame.setSize(1900,600);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
Sorry if that code was difficult to read. I believe the real root of my problem lies here:
XMLParser.BkTxCdAL.add((String) tbl.getValueAt(currentRow, 16));
None of those codes work. They simply pull the old value, not the new one. How can I fix this?

After doing more searching I finally found a solution that worked. The problem was that my table was still set as cell editing being turned on.
Adding this:
if(null != tbl.getCellEditor()){
tbl.getCellEditor().stopCellEditing();
}
Before attempting to save all my cells into the arrays worked perfectly.

Try to use the toString() method instead of a cast, as I remember, a String cast doesn't works when a value is predifened
